We explore motivational processes stemming from bicultural identity goals of being Turkish and being German by investigating the effect of identity goal incompleteness versus completeness in the two identity goals on the use of multifinal means to self-symbolize German-Turkish cultural identity goals. Individuals incomplete in either or both identity goals were more likely than individuals complete in both identity goals to engage in multifinal self-symbolizing via social media activity (Experiment 1) and helping (Experiment 2). Incompleteness regarding the two identity goals had an additive effect on effort and elicited distinct patterns of subjectively experienced incompleteness for German and Turkish cultural identity goals (Experiment 2). These findings offer new insights relevant for symbolic self-completion theory and goal systems theory.
